ウェブサービスコールでhtmlコンテンツを読み込みたいのですが、どのようにHTMLコンテンツをwebviewに読み込むことができますか？結果はSystem.out.println（data）に格納されます。 webviewでこのデータ値を読み取ることができません。コンストラクタも作成していますが、読み込めません。androidのhtmlコンテンツを読み込むには
public class Dashboard_Description__page extends AppCompatActivity {
ImageButton reader_back;
ArrayList<Reader_Model> actorsList;
String addCat;
ActorAdapter adapter;
WebView webView;
String alternate_id;
String bookmarkid;
String bookmarkfile;

String result;
String mimeType = "text/html";
String encoding = "utf-8";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_dashboard__description__page);
webView = (WebView) findViewById(R.id.webview);
webView.loadDataWithBaseURL(null, result, "text/html", "UTF-8", null);
// String summary = "<html><body>You scored <b>192</b> points.</body></html>";
//webView.loadData(getWebData(), "text/html", null);
WebViewClient yourWebClient = new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return false;
}
@Override
public void onPageFinished(WebView view, String url) {
webView.loadUrl("javascript:window.HtmlViewer.showHTML"
+ "(document.getElementsByTagName('pre')[0].innerHTML);");
}
};
// Get Web view
webView.getSettings().setJavaScriptEnabled(true);
// webView.addJavascriptInterface(new JSONReaderAsyncTask(), "HtmlViewer");
webView.getSettings().setSupportZoom(true);
webView.getSettings().setBuiltInZoomControls(true);
webView.setWebViewClient(yourWebClient);
// Load URL
webView.loadUrl(url);

htmlをロードすることができます。 –webviewを使ってhtmlファイルを読み込むことをお勧めします。 –
